TUESDAY, 8:45am: ESPN’s Mike Rodak and Mark Schwarz have a few more details on the incident, reporting that arrest warrants are expected to be issued in the coming days. Rodak clarifies (via Twitter) that those warrants aren’t expected today, but could be issued later in the week.
MONDAY, 10:35am: The brawl didn’t involve any current members of the Eagles, sources tell Les Bowen of the Daily News (on Twitter).
10:17am: The police report indicates that former NFL running back Curtis Brinkley was also involved, per John Gonzalez of CSNPhilly.com.
10:05am: Apparently, the investigation goes beyond McCoy. Detectives are investigating four NFL players for their alleged involvement in the brawl, per Dave Schratwieser of FOX29 (on Twitter). Sources tell Schratwieser (via Twitter) that the list of injuries includes a fractured skull, broken ribs, and a broken nose. It’s not immediately clear whether both officers have suffered those same injuries or if that injury list is a mash-up of what happened to the two men.
The argument apparently started when bottles of champagne were delivered to police officers before the players (link).
9:53am: Bills running back LeSean McCoy is under investigation for allegedly assaulting two off-duty Philadelphia police officers, sources tell ABC6. The incident is said to have occured around 2:30 a.m. on Sunday in Philly. McCoy has not been arrested, however, and neither has his friend who was also said to be involved in the altercation. 
McCoy played for the Eagles from 2009-14 before a blockbuster trade brought him to the Bills last year. McCoy, 28 in July, was held back by injuries in his first season with the Bills. The tailback ran for 895 yards off of 203 carries, good for 4.4 yards per contest. He also had three rushing touchdowns and two receiving scores. However, he missed one-quarter of the regular season, breaking his two season streak of playing in all 16 regular season games.
Although McCoy was not the electrifying playmaker in 2014 that he was in 2013, he still had a very productive season in terms of traditional stats for the Eagles, with 1,319 rushing yards and a 4.2 YPC average. The advanced metrics, meanwhile, showed a much sharper contrast between the two campaigns. That, in part, led to former coach Chip Kelly shipping him to Western New York for linebacker Kiko Alonso.
In 2013, McCoy was rated as the very best tailback in football according to Pro Football Focus (subscription required), racking up a 27.3 overall rating which was more than 8 points higher than the runner-up, Jamaal Charles. In 2014, however, McCoy was near the bottom of all qualified tailbacks with a fairly terrible -9.3 grade thanks in large part to his poor showing in the passing game.

The trade and subsequent extension for McCoy were a little puzzling from Buffalo’s perspective, even if you don’t factor in the advanced metrics. He just looked like a different back in 2014, although his counting stats were still respectable. But still, he showed flashes of his old self in 2015, and it looks like the Bills will be losing him for at least a couple of games in 2016, which they really can’t afford. The early details of this story reflect horribly on McCoy.
When are these atheletes going to be treated like regular people, instead of being put on a pedistal. I have a good friend first offence got 2 years in jail for assault and lost his job. These guys do it all the time and get nothing. They all should be kicked out of the NFL with no second chance. Give the good guys a chance to play.
If a Dr, lawyer, Nurse, cop and many others get charged with a felony do they get second chances? NO
Black privilege, must be nice. When a white guy hits a cop he goes to jail or gets shot.
